Publication number: 20230367257Abstract: An image forming apparatus includes an image forming device, an image bearer, at least one density sensor, a cleaning jig, and an insertion port. The image forming device forms a toner image. The image bearer bears the toner image to be transferred on a recording medium. The density sensor has a light-receiving surface to optically read the toner image. The light-receiving surface faces the image bearer constantly. The cleaning jig cleans the density sensor and includes a cleaner to contact the light-receiving surface. The cleaning jig is inserted through the insertion port into the body of the image forming apparatus and reciprocally moved to clean the light-receiving surface and is removed from the body of the image forming apparatus after the light-receiving surface is cleaned.Type: ApplicationFiled: May 8, 2023Publication date: November 16, 2023Inventor: Hirofumi FUJII
